DECABBONIZER AND GAS-SAVER .FOB- INTEENAL-COD/TZBUSTIUN ENGII'Q'ES.

To all-107mm it may cancer Be it known that I, li hcrmni. Prnnzcn'an SKI, a citizen of the United States, and aresidenii of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Inn proved Decarbonizer and Gas-Saver for InternalCombustion Engines, of which the following is a full, clear, and exact description.

This invention relates to internal com bustion engines and has for an object the provision of an improved attachment for preventing deposit of carbon on the cylinders of the engine.

Another object in view is to provide an attachment for an internal combustion engine when a maximum result is secured from a given supply of fuel.

A still further object of the invention is an attachment for an internal combustion engine connected with the accelerator pedal for adding to the explosive mixture auxilwater in addition to mixture by the cariary air and steam or the air supplied to the burcter.

In the accompanying drawing:

Figure 1 is a detail fragmentary side view of part of an engine and radiator with an embodiment of the invention applied thereto.

Fig. 2 is an enlarged fragmentary sectional view through lfig. 1 on line 22, the valve beingshown in a different position.

F ig. 3 is a sectional view through Fig. 2 on line 3-3, the same being on an enlarged scale and showing the valve in open position. i

In the construction of internal combustion engines for general use, and particularly for use on automobiles, a carbureter is provided for mixing the fuel, as for instance gasolene with air, and supplying this mite ture to the intake valve, which in turn directs the mixture to the various cylinders of the engine. A valve is usually provided between the carburetor and the engine somewhere in the intake manifold, said valve being controlled by a suitable pedal known as the accelerator pedal on automobiles. After the engine has been started and it is desired to secure more power the accelerator pedal is depressed and the valve between the engine and the carburetor is open more and more according to the speed or power desired, said opening permitting more fuel to be drawn through the carbureter into the Specification of Letters Yatent.

engine. By this construction and'arrangement the mixture drawn into the engine is controlled by he position in which the carbureter has been and the effect of depressing the accelerator pedal is merely to allow a larger volume to enter rather than to vary the quality of the mixture. In the present invention means ave been snpplied for automatically varying the quality of the mixture when the accelerator pedal has been depressed and at the same, time prevent carbonization.

Referring to the accompanying drawing by numerals, 1 indicates the uple of he manifold and 2 and 3 represent the distributing legs, leg 1 being connected in suitable manner with the carburetor 4. A. butterfly valve 5 is arranged on the upleg 1,

said valve being controlled by a lever 6,

which lever is pivotally connected with rod 7. Rod i is pivotally connected with double lever 3 journaled on the pivotal. support 9, which double lever 8 is resiliently held in a given position. by spring 10 and acted on by link 11 actuated by the accelerator pedal 12 for moving the parts as desired. l/Vhen the operator moves the pedal 12 as in dicated by the arrow, rod 7 will he pulled longitudinally against the action of spring 10 for opening valve 5, said opening being in proportion to the movement of the accelerator pedal 1". The construction just described is substantially t ordinary construction now in part of the present invention except in combination with the parts hereinafter fully described. The lever 8 in addition to actuating the link 11 actuates a link 13 pivot-ally connected at 14% nected at 15 :0 arm 16, arm 16 rigidly secured to valve plug 1'? oi the valve ine1nher 18. Valve member 18 is connected at 19 to the upleg 1 or the inanifoln and at to a tube 21, which may be of metal, rubber, canvas or other material as desired and ma be connected by threads or otherwise at 213 to the valve member 18. The tube 21 is connected to the overflow 22 of the radiator so as to receive steam or water from the radi- #LGIHIHOH USE and forms to lever 8 and pivotally con- I i used for clamping the tube 21 stood that any suitable connection may be used without departing from the spirit of the invention. The spring 23 is provided so as to positively move the arm 16 and the plug 17-t0 a closed position whenever permitted by the position of link 13 and associate parts. The closing: movement oi the plug is limited by the lug 31 on the lever 16 engaging the shoulder 32 on valve memher 18. ll ien the plug is operated by the treadle 12, through the medium of the lever 8, link 13 and lever 16, it will. be moved to full open position, as shown in 3, when the plug is in this position, its passage Way will at an angle to the passageway 28, as shown in said figure. This will cause an upward suction in the upleg l to draw the air and steam downwardly through the passageway :28. In the valve member 18 'one or more openings 29 are provided in the upper part and also one or more openings 30 are provided in the lower part as shown in Fig. 3, the same permittin the free entrance of a given quantity of air, while steam or water is supplied through the tube 21 to the sleeve said steam or water mining with the air as it enters the passageway 27 of plug 1?. This mixture of air and steam, or air and water, dilutes the combustible mixture from the carhureter and supplies'a given quantity of water or steam to the en gine for roventing the forming of carbon on the cy inders. In case the overflow pipe 21 should supply water instead of steam, said water will accumulate in the passageway 28 and will not flow into the carburetor when the valve 17 is closed, which is the case all the time except when the accelerator pedal 12 is depressed. In addition as the plug 17 opens air is immediately drawn in and mixes with the Water in case there is any water in the passageway 28', said mixture causing a vapor that will readily mix with the explosive mixture. It will also be evident that when the plug 17 opens any considerable amount of waie passing into the 'passageway 28 Will be discharged out through the aperture 30.

As above stalled the tube 21 is preferably connected with the overflow pipe 22, but may be connected with the upper part of the radiator without departing from the spirit of the invention. In either event it is desirable to lift small vent hole in the cap of the radi order to prevent undue -thc combustion is better than where pressure in the radiator and consequently in the passageway 28 which would cause an undesirable amount of steam or water to be supplied. It will-also be noted that the steam or water and air from openings 25) and 36 are supplied only when the accelerator pedal is depressed and in proportion to the amount of depression of said pedal and consequently in proportion to the opening of the valve lhcu the engine is running idle no auxiliary air or steam is provided through valve 18, but as soon as the pedal 12 is depressed additional air and steam is supplied which naturally will make the mixture poor, so thai a greater etlicicucy is secured as no addi'tional air and steam is provided.

lVhat I claim is:
